Abstract
The utility model discloses a power cable lifting device. The power cable lifting device comprises a lifting rack which is a parallelogram structure connected by a top horizontal beam, a bottom horizontal beam, a left inclined beam, and a right inclined beam. The acute angle of the parallelogram structure is from 45 to 60 degree. A fixing hole is disposed on the bottom horizontal beam. A suspension ring is disposed on the right end of the top horizontal beam. A vertical beam is arranged between the top horizontal beam and the bottom horizontal beam. The top horizontal beam, the bottom horizontal beam, and the vertical beam are all angle iron. A left inner inclined beam is disposed on the left inclined beam while a right inner inclined beam is disposed on the right inclined beam. The power cable lifting device with reasonable design and simple structure is capable of relieving friction damage and has good security.
Description
Technical field
The utility model relates to the electric power facility technical field, especially relates to a kind of electric power cable lifting device.
Background technology
Along with rapid economy development, the also fast development of industrial and agricultural production and resident living power utility, network load is increasing.In order to guarantee the safe operation of electrical network, need to aging circuit and equipment carries out large repairs and technological transformation, overhead ground wire need be promoted when overhaul and technological transformation, its method for improving has two kinds: a kind of is that little span overhead ground wire promotes, this kind working condition needs two people, the one man operation cucurbit, people overhead ground wire pickaback installs wire clamp.Another kind is that big span overhead ground wire promotes, and this kind working condition needs three people, the one man operation cucurbit, and two people overhead ground wire pickaback install wire clamp.More than above Lever Blocks must be carried on a shoulder pole with hanging in two kinds of methods, and the angle bar of ground load upside has a cutting rubbing power to the cucurbit chain, the cucurbit chain is because friction easily produces crooked, distortion, damage the useful life of Work tool greatly, reduce the coefficient of safety of Work tool, increased unsafe factor for personnel construct.
The utility model content
In view of this, the purpose of this utility model is to have proposed a kind of electric power cable lifting device in order to overcome the above problems, and is reasonable in design, simple in structure, can reduce frictionally damage and fail safe is good.
For achieving the above object, the technical solution of the utility model is:
A kind of electric power cable lifting device contains hoisting frame, and described hoisting frame is the parallelogram sturcutre that is formed by connecting by entablature, sill, left cant beam and right cant beam, and the acute angle size of parallelogram sturcutre is the 45-60 degree; Described sill is provided with fixing hole, and described entablature right-hand member is provided with suspension ring; Be provided with vertical beam between described entablature and the sill; Described entablature, sill and vertical beam are angle steel; Also be respectively arranged with cant beam in the interior cant beam in a left side and the right side on left side cant beam and the right cant beam.
The beneficial effects of the utility model:
Be provided with vertical beam between the utility model entablature and the sill, parallelogram sturcutre is divided into two triangles, and the acute angle angle of parallelogram is suitable, also be respectively arranged with cant beam and right interior cant beam in the left side on left cant beam and the right cant beam, these technical characterstics have all increased stability of structure in addition.Described entablature, sill and vertical beam are angle steel.
Other advantages of the present utility model, target and feature will be set forth to a certain extent in the following description, and to a certain extent, based on being apparent to those skilled in the art to investigating hereinafter, perhaps can from practice of the present utility model, obtain instruction.Target of the present utility model and other advantages can realize and obtain by specifically noted structure in following specification and the accompanying drawing.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.
As shown in Figure 1, the power line lifter contains hoisting frame, and hoisting frame is the parallelogram sturcutre that is formed by connecting by entablature 4, sill 1, left cant beam 2 and right cant beam 5, and the acute angle size of row quadrilateral structure is 45 degree; And sill 1 is provided with fixing hole, and by carrying on a shoulder pole, entablature 4 right-hand members are provided with suspension ring 6 with being bolted to when being convenient to work.Be provided with vertical beam 3 between entablature 4 and the sill 1, increased bulk strength.Entablature 4, sill 1 and vertical beam 3 are angle steel.The cucurbit chain passes through from suspension ring 6, and the frictional force between the two is little, is difficult for producing flexural deformation, long service life.Left side cant beam 2 is provided with cant beam 7 in the left side, and right cant beam 5 is provided with right interior cant beam 8.
The utility model has shown following advantage during use:
1, the utility model improved operating efficiency, reduced personnel labour intensity, increased the coefficient of safety of construction, distribute thereby can more reasonably carry out personnel, guarantee construction and personal safety to greatest extent.
2, the utility model adopts parallelogram sturcutre, and it is stressed average everywhere, is difficult for producing flexural deformation, long service life.
3, the utility model reasonable in design, simple in structure, can reduce frictionally damage and fail safe is good, it is applied widely, has good economic benefit after the popularization.
Explanation is at last, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, other modifications that those of ordinary skills make the technical solution of the utility model or be equal to replacement, only otherwise break away from the spirit and scope of technical solutions of the utility model, all should be encompassed in the middle of the claim scope of the present utility model.
